摘要
探讨了将粉煤灰磨细加工后用于煤矿注浆堵水的可能性;结合试验结果,进一步说明了加工后的粉煤灰可以改善浆体的结构、提高浆体的后期强度、降低浆体的泌水率。研究结果对注浆堵水材料的改进及粉煤灰的综合利用有理论上的指导意义。
This paper probes into the possibility of using ground fly ash into grouting material to plug water in collieries. According to the experimental tests, it was found that processed fly ash can not only improve the of structure plugging mass but also increase long - term strength of plugging mass and reduce the bleeding rate of grout,
